As a follow up, I have recreated the problem on 12.04 server. I have a 
10.04 guest that I cloned. The clone was reconfigured to use qxl and 
spice. In virt manager, there is no way to change the hypervisor from 
kvm to kvm-spice. Using virsh I changed the hypervisor to kvm-spice and 
started the guest.

As another test I left the hypervisor as kvm-spice and changed the video 
back to vnc/cirrus. I was able to start the guest and view the console 
without problem.

Testing other combinations, I found that video on cirrus and Display on 
spice allowed me to connect to the guest with spicec.

It would appear that the problem is with the qxl backend rather than 
kvm-spice. I now need to figure out how to get more logging out of kvm 
with the qxl video device.

Thank you,
